Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility. In existing system ABE (attribute based encryption) is used to maintain security. Attribute-based encryption is a type of public-key encryption in which the secret key of a user and the cipher-text are dependent upon attributes. In computing, data de-duplication is a specialized data compression technique for eliminating duplicate copies of repeating data. Related and somewhat synonymous terms are intelligent compression and single-instance storage. In this paper we studied the different attribute storage mechanisms as well as de-duplication system.

Cloud computing is a developing processing worldview empowering clients to remotely store their information in a server and give on-request benefits. With the rise of sharing classified corporate information on a cloud server, information security and protection turned into the basic issues for remote information stockpile. Secure client upholds information to get to control system must be given before cloud client has the freedom to outsource delicate information to the cloud for capacity. In the exhibit, numerous cryptographic calculations are utilized for encryption of the information. In this paper, we will research distinctive plans for encryption and possible solutions for their requirements that involve Attribute-based encryption (ABE), Key arrangement Attribute-based encryption (KP-ABE), and Cipher text attribute-based encryption (CP-ABE), also de-duplication methods.
